Y channel only. Y channel adjustments work best when the Lum Mix setting is set to the
right side to use YRGB processing vs the left side to use regular RGB processing.
Normally, most DaVinci Resolve colorists use the YRGB color corrector as you get a lot
more control of color balance without affecting overall gain, so you spend less time
getting the look you want.
Contrast Setting
The Contrast setting gives you control over the distance between the darkest and lightest
values of an image. The effect is similar to making opposing adjustments using the lift and gain
master wheels. The default setting is 50%.
Saturation Setting
The Saturation setting increases or decreases the amount of color in the image. The default
setting is 50%.
Hue Setting
The Hue setting rotates all hues of the image around the full perimeter of the color wheel.
The default setting of 180 degrees shows the original distribution of hues. Raising or lowering
this value rotates all hues forward or backward along the hue distribution as seen on a
color wheel.
Lum Mix Setting
The color corrector built into Blackmagic cameras is based on the DaVinci Resolve primary
color corrector. DaVinci has been building color correctors since the early 1980's and most
Hollywood films are color graded on DaVinci Resolve than any other method.
This means that your color corrector built into the camera has some unique and creatively
powerful features. The YRGB processing is one of those features.
When color grading, you can choose to use RGB processing, or YRGB processing. High end
colorists use YRGB processing because you have more precise control over color and you can
independently adjust the channels with better separation and more creative options.
When the Lum Mix control is set to the right side, you have the 100% output of the YRGB color
corrector. When you have the Lum Mix control set to the left side, you get 100% output of the
RGB corrector. You can set the Lum Mix to any position between the left and right to get a
blend of output from both the RGB and YRGB correctors.
Which is the correct setting to use? That's up to you, as color correction is a pure creative
process and there is no right and wrong, and the best setting is what you like the most and
what you think looks good!
Drag the sliders left or right to adjust Contrast,
Saturation, Hue and Lum Mix settings.
Synchronizing Settings
When connected, camera control signals are sent from your ATEM switcher to the Blackmagic
camera. If a setting is accidentally adjusted from your camera, camera control will automatically
reset that setting to maintain synchronization.
